A Complex Satellite Distribution System

My problem was this. 5 Bell ExpressVU satellite receivers. One Free-To-Air (FTA) receiver, primarily used for receiving NASA TV. In order to feed all this, I have two satellite dishes. The first one covers 83° and 91°. The second one covers 119°. I need to get the Bell satellites to 5 receivers, and I need to get all three satellites to the FTA receiver. Here’s a picture of my distribution system:


t’s a little unclear to follow in the picture, so here’s a schematic version that is a little clearer:


I have two SW44 switches to allow more than 4 ExpressVu receivers. The two SW44 switches are connected together using satellite-grade (up to 2GHz) splitters. The splitters I used have one DC path. Make sure that the DC path outputs are all connected to the same switch (it doesn’t matter which one). The splitters then connect to a pair of classic 2×4 switches (sometimes called 3×4 because there’s a third terrestrial signal input, which isn’t used). Outputs 1 and 2 basically pass on the 13v and 18v outputs from the LNBs on the ExpressVu dish. The third output from the switches, along with the line from the 119° dish connect to a DiSEqC switch. The DiSEqC switch then connects to the FTA receiver.

That’s it! 46 F connectors and a box of wire later! Make sure you use good quality connectors and cable. This many switches and connectors will degrade the signal strength, so you need to make sure you’ve got as little loss as possible. In my case, the signal strength dropped from around 90 to just over 80. Still very acceptable.
